Is the engine that Chevy runs in Nascar an LS or SB2?
What is it that makes the LS series engines so good? Antique push rod archetecture, but they outlast and out perform many higher tech engines. Please discuss.

NASCAR engines are race engines. Little to no relation to a production engine.
Part two, chev 8s are now and have been (since the 305) reliable.

The draw for me personally (even though I dont own one. But I wish I had one in more than a couple different cars.) is the output of power compared to its dimension and weight. Reliability also seems to be a key factor. You can have quite a bit of power out of one while still not stressing the engine itself too bad at all. Another reason I also like them is the simple fact of displacement, more usable torque.
No idea on the NASCAR question though lol sorry!

Nearly 50 years of refinement.

Oh, another good point. You might say that push rod engines are antique and all that but after nearly 50 years the push-rod engine has been refined to the point that theres not really much wrong with it at all. IMO anyway...

305s are dead nuts reliable. Anemic, but reliable. You're thinking of the self-destructing 267 from the 70s.

They may be shooting blanks but they are ALWAYS shooting blanks. Pretty reliable.
